Popliteal Vascular Ultrasound

Your doctor has requested an ultrasound of your popliteal artery that is located behind your knee. Ultrasound technology is safe and images arteries and veins. There is no radiation or injection of chemicals. This procedure is performed to evaluate the popliteal artery for possible aneurysm or blockage.

At the Cedars-Sinai S. Mark Taper Foundation Imaging Center, we have a specialized team of physicians and technologists who are experts in ultrasound technology.

  • Leave valuables and jewelry at home. Please do not eat or drink six hours before your exam. You may take any scheduled medication with a sip of water.

During Your Exam

A vascular ultrasound of the popliteal artery behind the knee. The circular structure in the lower middle part of the image is the artery, with a dotted white line across it.

  • You will be lying on the exam table on your back with your hands at your sides. The technologist will apply a warm gel behind your knee and a transducer or a small microphone will be used to examine your arteries.
  • You will hear the sound of moving blood during the exam. Do not be alarmed; it is harmless. The exam will take approximately 60 minutes.

After Your Exam

Your study will be read by a physician who will send the results to your doctor. Your doctor, who ordered the study, will explain the findings to you. If you have problems related to your procedure, please call 310-423-8000
